Biol 361 Worksheet: Action potential propagation 1 Name: Student #: 1. Consider the following 3 membrane properties of a cell: R m , R i , C m . For each of the 3 properties, describe how increasing and decreasing them would affect the propagation of signal in an axon. a) increasing R m b) decreasing R m c) increasing R i d) decreasing R i e) increasing C m f) decreasing C m 2. Action potential speed can be modified by 1) myelinating the axon, and 2) changing the diameter of the axon. a) How does myelin affect R m ? b) How does myelin affect R i ? c) How does myelin affect C m ? d) How does increasing axon diameter affect R m ?

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
